Outstanding Nevada geologist to lead the Nevada Bureau of Mines and Geology

Image001

Dr. James E. Faulds will be replacing Dr. Jonathan G. Price as State Geologist and Director of the Nevada Bureau of Mines and Geology (NBMG) at the University of Nevada, Reno (UNR) when Jon retires at the end of June. Between now and then, Jim and Jon will be sharing duties of the position, as we transition to Jim’s leadership.

Jim, who has been with NBMG since 1997, is an expert in structural geology, tectonics, and geothermal systems. He has published widely on extensional and strike-slip tectonics, nonmarine salt deposits, and structural controls on geothermal systems, including relations between current geothermal activity and young epithermal mineral deposits. He has mapped dozens of quadrangles in Nevada, including some in the Searchlight mining district in southern Nevada, the Carlin trend, the Walker Lane, and several known geothermal resource areas. His geothermal research has been instrumental in developing more sophisticated exploration strategies for geothermal systems. He has also taught courses in structural geology, tectonics, geothermal exploration, and field geology, including serving as Director of UNR’s geology field camp for 5 years. He has served as advisor for 14 graduate students while at UNR. He is also the current President of the Nevada Petroleum Society.

Jim earned his B.S. (with highest honors) at the University of Montana, his M.S. at the University of Arizona, and his Ph.D. at the University of New Mexico. He held postdoctoral research positions at the University of Nevada, Las Vegas and at the University of Southern California and was on the faculty at the University of Iowa before joining NBMG.

Dr. Price can be credited with greatly enhancing the NBMG in his 24 years of stewardship and developing it into one of the best state geological surveys in the nation. Our understanding of many facets of Nevada geology has been greatly accelerated under Dr. Price’s leadership. Jon will continue as a member of the Bureau with emeritus status.

Please join us in welcoming Jim to his new roles as the NBMG Director and the State Geologist of Nevada.

Former NBMG geologist featured in Earth Magazine

Kyle House (former research geologist at NBMG, now with USGS) and “Preliminary Surficial Geologic Map of Clark County, Nevada” (NBMG Open-File Report 10-7) are featured in the February 2012 issue of Earth Magazine.

View the article on Kyle’s blog:

The map, published in 2010, is available on the NBMG website at http://www.nbmg.unr.edu/sales/pbsdtls.php?sku=OF10-%207

Erionite in the news again

In the February 2012 issue of Earth Magazine, North Dakota state geologist discusses the health risks of erionite.

NBMG also previously reported that there was recent interest in the health hazards of erionite and therefore made Bulletin 79 available free on the web:

Digital Historical Topographic Maps Now Available for Nevada

USGS has just posted its historical topographic map collection for the state of Nevada online for download by the public. This map collection includes over 3,634 historic maps across the state with some maps dating back over 100 years.  All published map scales are available, including:

7.5-minute (1:24,000), 15-minute (~1:63,000), 30-minute (1:100,000), and
1×2 degree (1:250,000), and have been scanned at a higher density than previous DRG editions.

You are invited to access the collection and download any of the maps.

To get the maps, visit the USGS Store site at:
store.usgs.gov <http://store.usgs.gov/>
Then click on the “Map Locator & Downloader” in the center of the page.

From there you can locate your favorite maps in AZ by searching by map or place name or by pan/zoom on the viewer.  Maps are available as GeoPDF® files (viewable in your Adobe reader).

Lots of additional information is available on the maps and the program that produced them.  For example:

1. Information about the USGS historical topographic map collection and the historical quadrangle scanning project can be found here:
        http://nationalmap.gov/historical/
        http://pubs.usgs.gov/fs/2011/3009/

2. We have a 19 minute video from the September 2011 International Map Trade Association Conference on distribution of USGS historical topo maps:
        http://gallery.usgs.gov/videos/465

3.  See a press release on the historical topographic map collection.

  The article pre-dates the Arizona map release but provides additional information on the project:
        http://www.usgs.gov/newsroom/article.asp?ID=3024

Note that while looking around the USGS Store and the National Map web pages, you may also come across new maps for Nevada called US Topo. These are new topographic maps now in production for Nevada (shown as red hachuring).  These can also be downloaded through the USGS Store and are available as GeoPDF® files.  There will be further announcements on US Topo as production wraps up for Nevada in the near future. US Topo will be produced over USFS areas. (‘Beta’ versions of the topo (which shows as yellow hachuring) will be taken off line due to very minimal content specifications.)

US Topo is the next generation of digital topographic maps from USGS.  Arranged in the traditional 7.5-minute quadrangle format, digital US Topo maps are designed to look and feel like the traditional paper topographic maps for which the USGS is so well known. At the same time, US Topo maps provide modern technical advantages that support wider and faster public distribution and enable basic, on-screen geographic analysis for all users.

US Topo maps are available free on the Web. Each map quadrangle is available as a GeoPDF® file created from key layers of geographic data – orthoimagery, roads, geographic names, contours and hydrographic features – found in the National Map, which is a nationwide collection of integrated data from local, State, Federal, and other sources.

Like the historical topographic map collection, we have lots of information on US Topo and related products:

         1. US Topo information is online at
                http://nationalmap.gov/ustopo/
                http://pubs.usgs.gov/fs/2009/3108/

        2. Additional fact sheets about National Map products and services are at
                http://nationalmap.gov/factsheets.html

        3. News items and tweets on the USGS National Geospatial Program are at
                http://nationalmap.gov/tnm_news.html
                http://twitter.com/#!/USGSTNM

         4. USGS values your comments and suggestions about new US Topo and historical topographic maps. Please submit comments online at
                http://nationalmap.gov/ustopo/ustopo_feedback.html
